FAQ
What is the maximum operating frequency of the TMS320DM648CUT1?
The TMS320DM648CUT1 is characterized for operation at 900 MHz (1.11 ns cycle time), delivering 7200 MIPS. While the DM648 family supports up to 1.1 GHz, the CUT1 speed grade is specifically rated for 900 MHz operation under commercial temperature conditions. This rating is confirmed in TI's SPRS372H datasheet Section 2.1, Table 2-1.
Does the TMS320DM648CUT1 support DDR2 memory, and what are its interface specifications?
Yes, the TMS320DM648CUT1 integrates a 32-bit DDR2 SDRAM controller supporting 512 MB address space with 1.8-V I/O. It operates at DDR2-400 speeds (200 MHz clock), includes programmable read/write leveling, and supports JEDEC-standard DDR2 features including auto-precharge and self-refresh. These capabilities are detailed in Section 6.9 of the SPRS372H datasheet.
How many video ports does the TMS320DM648CUT1 have, and what standards do they support?
The TMS320DM648CUT1 includes five configurable 16-bit video ports (VP0–VP4), each supporting both capture and display modes. They provide glueless interface to devices compliant with CCIR601, ITU-BT.656, BT.1120, SMPTE 125M/260M/274M/296M, and other broadcast video standards. Each port has a 5120-byte buffer splittable between dual channels (A/B), as specified in Section 6.11 of SPRS372H.
Is the TMS320DM648CUT1 pin-compatible with the TMS320DM647CUT1?
Yes, the TMS320DM648CUT1 and TMS320DM647CUT1 share identical 529-pin nFBGA (ZUT) packaging, pin assignments, and power sequencing requirements. They are functionally pin-compatible, allowing drop-in replacement in existing DM647 layouts - though DM648-specific features (dual SGMII, larger L2) require firmware and board-level validation. This compatibility is documented in TI's device comparison tables (SPRS372H Section 2.1).
What boot options are supported by the TMS320DM648CUT1?
The TMS320DM648CUT1 supports multiple boot modes including EMIFA NAND flash, EMIFA NOR flash, SPI EEPROM, and UART host download, controlled via BOOTMODE[3:0] pins. An on-chip 64 KB ROM bootloader initializes the device and loads application code into L2 or external memory. Boot configuration details and vector tables are defined in Section 3.2 of the SPRS372H datasheet.
